BIG KAISER, a leader in premium high-precision tooling systems and solutions for the aerospace, automotive, energy, medical and watch-making industries, introduces the EWD Smart Damper, a precision boring head with innovative, patented damping technology and digital control.

The EWD Smart Damper damps vibrations and reduces chatter in deep-hole finish boring – thus achieving better surface finishes and improved metal removal rates.

For precision machining of deep bores, it has previously been necessary to choose low cutting data in order to prevent vibrations, which massively increases processing time. The EWD Smart Damper overcomes this problem, and enables high cutting parameters to be used. This means that extremely short turnaround times can be achieved, which improves productivity by up to a factor of ten.

Tests have shown that deep holes free of vibration can be bored, with dramatic time savings. For example, with a projection length of 410mm working with steel with a cutting speed of 450m/min, a feed rate of 150mm/min can be achieved.

As well as the damping features, the EWD Smart Damper is also equipped with the latest digital technology. The tool has a large screen, which clearly shows the set diameter to an accuracy of 0.001 mm, thus helping to minimize operator errors and removing the need for complicated Vernier markings. The digital display can be reset to zero at the push of button and has an auto power off function, while the current position of the cutting edge will be shown automatically again due to direct path measurement when the tool is switched on.

“With the EWD Smart Damper we have increased productivity tenfold for deep holes, while applying the latest digital technology developed in our in-house electronics lab,” says Peter Elmer, CEO of BIG KAISER. “Due to its dynamic vibration damping, the EWD Smart Damper offers time savings and longer life than conventional solutions.”

The EWD Smart Damper is compatible with BIG KAISER’s modular CK system, which means that the length of tool combinations can be freely selected up to a maximum of ten times the diameter. Thanks to different insert holders, different diameters can be processed – for example, between 68 and 150mm for the EWD 68 Smart Damper.
